Perform accurate measurements on any substrate: metal, semiconductor or glass

Perform accurate measurements on any substrate:  metal, semiconductor or glass | Free Spectroscopic Ellipsometry Workshop

For anyone that is performing coatings on glass, this workshop would be an ideal opportunity to gain an introduction to Spectroscopic Ellipsometry.  J A Woollam’s patented technology allows accurate measurements on any substrate: metal, semiconductor, or glass. On transparent substrates, the alpha-SE® measures depolarisation to correct for light returning from the backside of the substrate. This unwanted light can confuse other ellipsometers, but the alpha-SE® ensures accurate optical constants.  See alpha-SE in this video

 

Application engineers from J A Woollam will give talks on the following topics:

  • Theory and Fundamentals of Spectroscopic Ellipsometry
  • Applications and Data Analysis Examples of Spectroscopic Ellipsometry
  • Overview of J A Woollam Ellipsometers including the alpha-SE Ellipsometer

 

There will also be a demonstration of the alpha-SE Ellipsometer and we can also do basic measurements on the day, so please do get in touch to get a sample submission form (any we can’t do on the day we will take away to do at the US factory).

 

This free of charge workshop is aimed at both experienced ellipsometry users as well as people new to ellipsometry.  The format of the workshop includes an introduction, fundamentals of ellipsometric data analysis, and an overview of ellipsometric applications in both research and production. New emerging applications are highlighted.

 

The workshop will be held at the MTIF Research Centre at Nottingham Trent University on Monday 13 September 2021.  It has been organised by Quantum Design who represent J A Woollam in the UK and Ireland.  Quantum Design UK and Ireland is part of the Quantum Design International (QDI) group.  QDI is a global laboratory equipment manufacturer. The company distributes scientific and industrial instrumentation through an international network, with subsidiaries in every major technological centre around the world.  QDI’s success in distributing scientific products comes from more than 30 years’ experience in manufacturing and distributing its own industry-leading materials characterisation systems.   Find out more about us and our extensive product range at www.qd-uki.co.uk

UK-REACH is now in force!

If you’re based in Great Britain and manufacture, import, sell or distribute chemical substances or mixtures you’ll need to follow the UK REACH regulation and comply with a number of new obligations.

What’s next?

You can now create an account on the new IT system ‘Comply with UK REACH’ in order to begin the ‘grandfathering’ of Registrations, Authorisations and PPORD’s and also notify substances imported from the European Union or European Economic Area by submitting a Downstream User Import Notification.

Need to grandfather a REACH Registration?

You only have only 120 days post Transition Period to complete this process, so act now to ensure you meet this deadline (30th April 2021).

Are you a Downstream User and need to notify substances?

The DUIN’s must be submitted by 27th October 2021.

If you’re an EU/EEA based manufacturer or formulator and need to retain access to the UK market you can appoint an ‘Only Representative’ to act on your behalf and fulfill the obligations of your UK importers.

Yordas can be your Only Representative for UK REACH

BASF are now using circular feedstocks to produce sustainable plasticisers

The BASF ChemCycling™ initiative aims to manufacture products based on chemically recycled plastic waste. Working with selected partners they use a process called pyrolysis to transform plastic waste into a secondary raw material. The resultant oil is then fed into BASF’s integrated production plants and allocated to selected sales products, which subsequently become ‘sustainability enablers,’ third-party certified according to a mass-balance approach.

The second strategy uses renewable raw materials, such as biogas derived from organic waste and vegetable oils, to act as feedstocks for biomass balanced (BMB) chemicals that use less fossil fuels and reduce CO2 emissions – compelling features for manufacturers and consumers alike.

BTC Europe are now able to offer the sustainable plasticiser grades including Hexamoll® DINCH – ccycledTM, Hexamoll® DINCH BMB, Palatinol® N BMB, Palatinol® 10P BMB, Plastomoll® DOA BMB.

The plasticisers of the Biomass Balance and ChemCycling™ portfolio have the same product properties as the regular plasticisers. Customers can therefore easily switch to the more sustainable alternatives in already established customer formulations, for example by using Hexamoll® DINCH in children’s toys.

Raw material availability and price hikes may end up as 2021’s biggest issue

Lack of availability of key raw materials and packaging, and significant price increases are causing significant disruption to the coatings and printing ink industries in the UK and across Europe.

There are four significant trends affecting raw material prices:

  • Strong global market demand has led to shortages on many raw materials
  • The oil price has risen by 58% since November (currently $68 a barrel)
  • The global shortage of shipping containers has led to a sharp rise in transport costs from Asia to Europe thus further restricting supplies to Europe.
  • Additional non-tariff costs related to the new UK customs arrangements with the EU are adding to the cost of imported raw materials into the UK from Europe.

However, there are also some specific reasons for some of the recent increases.

Solvents are one category where prices are going through the roof.  Some examples in BCF’s monthly raw material prices survey shows the largest increases in solvent prices in January 2021 versus 12 months ago are acetone (123%) n-butyl acetate (91%), IPA (41%) and n-butanol (54%). A critical issue here are two force majeures at major chemical plants producing butyl acetate.

In January, BCF issued a press release reporting sharp price increases for epoxy resins, of as much as 60% in Q3 2020. Similar problems are affecting the market for polyester resins with factory closures in Singapore and Sweden as well an explosion at a factory in China adding to the difficulties. There are also problems with bisphenol-A with stocks being diverted to polycarbonates. Neopentyl glycol and methanol are also both reported to be in short supply.

Concerns have also been raised about pigment shortages, such as red and yellow iron oxide.  Plastic polymers are also in short supply, affecting availability and prices of packaging, with 5L paint cans 10% higher than at the same period last year, and tin plate has had a similar increase.

“Given that raw materials and freight comprise the majority of the overall cost to produce paints, coatings and printing inks, this trend will have a major impact on the operations of BCF member companies,” said BCF CEO Tom Bowtell. “Where possible, BCF members will seek to mitigate higher costs via internal process optimisation measures, alternate sourcing and increased efficiencies”.

BCF grows influence on global coatings industry stage

At the annual meeting of the World Coatings Council in March 2021, Tom Bowtell, Chief Executive of the British Coatings Federation, was elected Vice President.

The World Coatings Council is made up of members representing associations from the United States, China, European Union, Brazil, Mexico, Australia, Japan, Canada, South Africa, New Zealand, Turkey, France, Germany, and the United Kingdom.

The Council, which provides a forum for exchange and cooperation on major issues and priorities facing the industry, has established itself as a global voice with the United Nations, Governments and NGOs.

“Following the UK’s decision to leave the EU, the BCF are keen to contribute to the significant issues affecting the coatings industry worldwide. It is a great honour to have the trust of my industry colleagues from associations around the world,” said Tom Bowtell.

One of the most important issues for the coatings industry to focus on is the sustainability agenda. With the UK hosting United Nations COP26 later this year, it is an opportune moment for the BCF to be involved with helping the World Coatings Council evaluate the coatings industry successes and challenges against EU Sustainable Development Goals, in a report which will be published later this year.

Andy Doyle, President of the World Coatings Council and CEO of the American Coatings Association, commented: “Tom’s election as Vice President of the World Coatings Council was unanimously supported by industry colleagues, and I’m delighted to have such an experienced and proactive deputy in my final year as President.”

It is expected that after a 12-month term as Vice President, Tom will take over the role of President at the next annual meeting of the WCC in March 2022.

New compact recirculating chiller

/// IKA is launching a new device class, with the RC 2 lite

Staufen, April 12, 2021 – IKA is adding a new device class to its portfolio of recirculating chillers. The RC 2 lite is elegant, compact and powerful and is a perfect addition to rotary evaporators, reflux coolers and cold traps.

The RC 2 lite is new product class in addition to the well-known basic and control product ranges. 400 watt cooling capacity and a pump pressure of 0.35 bar: the new recirculating chiller focuses on the essentials in every respect. This makes it space-saving, powerful and extremely economical. It is ideal for simple cooling tasks down to -10 °C and as a supplementary device to rotary evaporators, reflux coolers and cold traps.

Thanks to the minimum filling volume of just one liter, the RC 2 lite is able to carry out temperature changes very quickly if necessary. Its working volume of 2.5 liters, which is quite large considering its compact size, enables a large number of external applications without the need for refilling. The highlight for users is the stainless steel mesh filter. It is easily accessible and just as easy to clean. Its ergonomic design, which is typical for all IKA products, thus contributes to the reliable performance and long service life of this basic device.

For the cooling of the RC 2 lite, IKA consistently relies on the natural refrigerant R 290, which is already being used in the demand-controlled chillers RC 2 GREEN basic and control as well as RC 5. It is one of the pure hydrocarbons, has a very low global warming potential and promises a long service life for the device, even with future usage requirements.

The RC 2 lite offers everything a good recirculating chiller needs. Its powerful pressure and suction pump enables the simultaneous operation of several applications as well as external open applications and the fill level, in the reservoir, is always in full view thanks to the large, illuminated sight glass.
